Newbie- basic Q's on me new motor!

Yes, it's where you initialize the system to start taking notes of your current wheel rotation speed and later comparing it to actual data.

Even if you don't get any warning messages, you may want to check the tyre pressures from time to time, and correct them if you see any inflation/deflation (for example, as small as 1 or 2 psi of difference, which would not trigger the warning message). Whenever you do that, don't forget to hit that button and reinitialise the system.

Hi serdar..

So the idea being, you first (cold tyres) get tyres to the correct psi figure -if you could tell me/ great- then hit this button?

Actually, I seem to recall (just now as I type).. that the last thing my dealer did whilst doing final checks, was he noticed a tyre warning sign on the dash. Immediately knew what it was, he reassured me (3x new tyres having just been fitted = car hadn't recognised the pressures, or something/ needed re-calibrating) & sat in driver's seat prodding the screen until warning gone >> all set, & I drove off in my "new" car.

If my photo above of the screen, is precisely where he was, then this will mean in all likelihood the tyres pressures were calibrated by him then/ only 4 months ago. And therefore I shouldn't press calibrate then, now then-?

Thanks, Zoot

If you have a look in the fuel filler cap or on the pillar between the front and rear doors the tyre pressures will be on a plate. It will give you options for if you want eco setting (usually higher than normal to get less rolling resistance for higher mpg) or comfort setting. You choose the setting that best matches your carrying weight i.e. if its just you in the car with a bit of luggage you choose that one or if you regularly carry passengers then choose that one.

Even if the dealer has calibrated the tyres 4 months ago I would still check the tyres regularly for pressure and then calibrate as there are a number of factors that affect tyre pressure such as temperature, road quality, driving style etc so you want to make sure the system can detect any changes so you can sort it. At the end of the day the tyres are the only contact patches between the car and the road so make sure they're good and the car will look after you.

Yes, that's the procedure.

Correct psi figure depends on axle weight (front and rear differs) and the weight you're carrying (people and the stuff you loaded).

The figures recommended by the manufacturer are shown on a label you can find on the inside of the B-pillar. Don't remember exactly which side, but just open both front doors and you'll see it on the left or on the right.

There will be three different value sets, one for the low/medium load & eco ride, one for the low/medium load & comfort ride, and finally one for the full load. In all of those sets, the front and rear should likely be different.

There's no other menu item related to tyre pressure monitoring system, so that's where he did a reset. And no, you shouldn't do one now without checking and correcting the pressures. If you want, you can perform a check & correction as needed, then hit calibrate.
